Okay it says I need to make my own PGP public key but doesn't explain how exactly so maybe I did that wrong idk?
Which one of the above mentioned tutorials did you follow and what error message are you getting so we can help you? Creating your own key-pair isn't supposed to be that hard but it depends on the tool you are using.
Out of curiosity of I use a hardware wallet like ledger nano s via electrum desktop app that is has not had PGP verification and worse case scenario no one can technically access my bitcoin that's on my hardware wallet. It'd simply be the pain in the ass of removing the software that's corrupted on the computer it was used on if I'm not mistaken?
Technically, even if you download a fake copy of Electrum it won't be able to steal your coins from your hardware wallet
without your permission.
